If you append either:
print
or
import sys; sys.stdout.flush()
after your two lines above, you'll get the output. (The first with a
trailing newline, the latter without.)
I'm guessing that sys.stdout.close() would also work, but wouldn't
be very useful to you.
That should make the reason for the behaviour obvious.
( You don't get it in the interpreter window, because the line gets
flushed when it prints out a '>>>' prompt for the next input line.)
Is it a bug?
I'ld vote no -- it matches exactly what would happen if you had a
script writing to a file, or executed a script on the unix command line
(so you wouldn't get any prompts to the terminal) except that sys.stdout
would get flushed and closed at program termination.
